A hydraulic rod 54 is fixedly connected to the right section of the cross bar 52. A second motor 55 is fixedly installed on the top of the hydraulic rod 54. The movable block 53 is movably clamped inside the long slot 21. The output end of the second motor 55 is fixedly connected to the left side of the housing 2. The telescopic end of the hydraulic rod 54 is fixedly connected to the right side of the cross bar 52.

[0023] The hydraulic rod 54 is started, and the hydraulic rod 54 increases the stroke downward, and the triangular block 51 is pushed downward by the cross bar 52, and the movable block 53 also moves downward in the long groove 21. When the movable block 53 slides away from the position of the long groove 21, the second motor 55 is started, and the second motor 55 is controlled to rotate clockwise or counterclockwise to determine the concrete discharging direction. A stepped shape with a drop is formed between the shell 2 and the long groove 21, which is convenient for discharging. This solves the problem that the traditional mixing equipment has no inclined surface drop to assist in the discharging process, which causes the concrete on both sides of the shell 2 to easily gather in the middle position, causing concrete accumulation and insufficient discharging.

[0024] The bottom of the housing 2 is provided with a long slot 21, and the top of the housing 2 is movably provided with two electric plates 22;

[0025] The two electric plates 22 are started and closed, and a closed cavity is formed between the two electric plates 22 and the shell 2, which can prevent the problem of raw materials splashing during the stirring process.

[0026] Among them, the number of transmission devices 3 is two and they are symmetrically installed on the left side of the housing 2. The two transmission devices 3 include two first motors 31, the two first motors 31 are fixedly installed on the left side of the housing 2, the output ends of the two first motors 31 are connected to the first rotating wheels 32, the outer edges of the two first rotating wheels 32 are movably sleeved with belts 33, the other ends of the two belts 33 are movably clamped with two second rotating wheels 34, the left and right sides of the two second rotating wheels 34 are fixedly connected with first bevel gears 36, the outer edges of the two first bevel gears 36 are movably sleeved with fixing blocks 35, the outer edges of the two first bevel gears 36 are meshed with second bevel gears 37, a round rod 39 is fixedly installed between the two second rotating wheels 34, a universal shaft 38 is fixedly installed between the two round rods 39, the right ends of the two fixing blocks 35 are fixedly connected to the housing 2, the two second bevel gears 37 are fixedly connected to the left end of the rotating shaft 41, and the installation position between the first bevel gear 36 and the second bevel gear 37 is vertically installed;

[0027] The rotation of the two first motors 31 drives the two first rotating wheels 32 to rotate, and the rotational force is transmitted to the second rotating wheel 34 through the belt 33. The two second rotating wheels 34 further drive the two first bevel gears 36 to rotate, and then the two second bevel gears 37 installed vertically thereto can also rotate, thereby driving the two rotating shafts 41 of the stirring device 4 to rotate. The first motors 31 of the two symmetrically installed transmission devices 3 are started at the same time, and a coaxial rotation function is formed through the round rod 39 and the universal shaft 38 between the two second rotating wheels 34, thereby amplifying the torque and improving the stirring effect.

[0028] The stirring device 4 includes a rotating shaft 41, which is rotatably mounted inside the housing 2, and a plurality of fixing rings 42 are fixedly mounted on the outer edge of the rotating shaft 41, and two connecting rods 43 are fixedly connected to the outer edges of the plurality of fixing rings 42, and stirring blades 44 are fixedly mounted on the tops of the two connecting rods 43;

Under the extension effect of the fixing ring 42 and the connecting rod 43, the stirring blade 44 can fully contact with the raw materials in the shell 2 during rotation, thereby achieving more uniform stirring.

[0030] Working principle and usage process:

[0031] When using the utility model, firstly, the raw materials are put into the interior of the housing 2 according to a certain ratio, and the two electric plates 22 are started to close together, so that a closed cavity is formed between the two electric plates 22 and the housing 2;

[0032] At this time, the two transmission devices 3 are started, and the two first motors 31 rotate to drive the two first rotating wheels 32 to rotate, and the rotational force is transmitted to the second rotating wheel 34 through the belt 33. The two second rotating wheels 34 further drive the two first bevel gears 36 to rotate, and then the two second bevel gears 37 installed vertically therewith can also rotate, thereby driving the two rotating shafts 41 of the stirring device 4 to rotate. The first motors 31 of the two symmetrically installed transmission devices 3 are started at the same time, and a coaxial rotation function is formed through the round rod 39 and the universal shaft 38 between the two second rotating wheels 34, thereby amplifying the torque and improving the stirring effect.

[0033] The rotating shaft 41 is driven to rotate by two sets of transmission devices 3. Under the extension of the fixing ring 42 and the connecting rod 43, the stirring blade 44 can fully contact with the raw materials in the housing 2 during rotation, so as to achieve more uniform stirring.

[0034] After the mixing is completed, the hydraulic rod 54 is started, and the hydraulic rod 54 increases the stroke downward, and the triangular block 51 is pushed downward by the cross bar 52, and the movable block 53 also moves downward in the long groove 21.
